Hi Deepa, Once the GTT order is triggered or deleted, it is gone from the GTT order queue. You will have to create a new order altogether.
When the GTT order is triggered, the order is sent to the exchange and deleted from the GTT order queue. The order remains with an exchange for 1 trading day (same day). If it doesn't get executed, it is also get deleted from the exchange order list. In this case, you have to place a new GTT order.
